Answer 1

Answer:

when 5 is subtracted from length and breadth of rectangle the perimeter becomes 26 what is the mathematical form of the statement?

options

x - y =8

x + y=8

x + y =23

2x + y =21 Answer

Answer 2

Step-by-step explanation:

$\bf{Here \: we \: go!!}$

=>Let the length be x-5 and breadth be y-5.

TO FIND:-

=>The mathematical form of the statement.

$\bf\overbrace{Understanding \: The \: Concept}$

According to the question,

=> We know that length is x and breadth is y. From this we can find the mathematical statement by using the Perimeter of rectangle formula,

$\bf{ = > 2(l + b)}$

$\huge\bf\underline{Answer}$

$\bf{26 = 2(x - 5 + y - 5)}$

$\bf{26 = 2(x + y - 5)}$

$\bf{ \dfrac{26}{2} = x + y - 10}$

$\bf{13 = x + y - 10}$

$\bf{23 = x + y}$

Therefore, The mathematical statement is 23 = x + y.
